Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to an energy-saving air drying device. Background Technology

[0002] Currently, air drying equipment mainly consists of two double tanks filled with adsorbent. The two tanks alternately turn the airflow on and off, performing drying and regeneration operations in turn, so that the compressed air can continuously contact the unsaturated adsorbent to achieve the purpose of dehumidification and drying.

[0003] After the adsorbent inside the tank undergoes regeneration, its temperature rises. Since the adsorption capacity of the adsorbent decreases with increasing temperature, the drying efficiency of the adsorbent decreases after regeneration. Utility Model Content

[0004] To reduce the decrease in adsorbent drying efficiency, this application provides an energy-saving air drying device.

[0005] The energy-saving air drying equipment provided in this application adopts the following technical solution:

[0006] An energy-saving air drying device includes three tanks, an input pipe, and an output pipe. The top of each tank is connected to a drying outlet pipe, a regeneration outlet pipe, and a cooling outlet pipe. The bottom of each tank is connected to a drying inlet pipe, a regeneration inlet pipe, and a cooling inlet pipe. The drying inlet pipes are all connected to the input pipe, and the drying outlet pipes are all connected to the output pipe. A cooling assembly is shared on the input pipe and the cooling inlet pipe to reduce the gas temperature. A microwave transmitter and several adsorption cylinders are installed inside each tank. The adsorption cylinders are arranged in a circular array around the microwave transmitter, and an adsorbent layer is provided inside each adsorption cylinder for adsorbing moisture.

[0007] By adopting the above technical solution, the three tanks respectively perform compressed air drying, adsorbent regeneration, and adsorbent cooling. When the tank is in the compressed air drying state, the regeneration inlet pipe, regeneration outlet pipe, cooling inlet pipe, and cooling outlet pipe are all cut off, while the drying inlet pipe and drying outlet pipe are open. At this time, the compressed air in the input pipe enters the tank along the drying inlet pipe, and the compressed air contacts the unsaturated adsorbent to achieve dehumidification and drying. The dried compressed air enters the output pipe through the drying outlet pipe. When the adsorbent in the tank is saturated, the tank is adjusted to the adsorbent regeneration state. At this time, the drying inlet pipe, drying outlet pipe, and cooling outlet pipe are open. Both the drying inlet and cooling outlet pipes are in a cut-off state, while both the regeneration inlet and regeneration outlet pipes are in a conductive state. Simultaneously, the microwave transmitter is activated to allow the moisture in the adsorbent to be discharged through the regeneration outlet pipe. After the adsorbent in the tank is regenerated, the tank is adjusted to an adsorbent cooling state. At this time, the drying inlet, drying outlet, regeneration inlet, and regeneration outlet pipes are all in a cut-off state, while both the cooling inlet and cooling outlet pipes are in a conductive state. The gas cooled by the cooling component enters the tank through the cooling inlet pipe to purge the adsorbent, thereby cooling the adsorbent. The gas after purging the adsorbent is discharged from the tank through the cooling outlet pipe, reducing the decrease in adsorbent drying efficiency.

[0008] Preferably, a drying inlet valve is provided on the drying inlet pipe, a drying outlet valve is provided on the drying outlet pipe, a regeneration inlet valve is provided on the regeneration inlet pipe, a regeneration outlet valve is provided on the regeneration outlet pipe, a cooling inlet valve is provided on the cooling inlet pipe, and a cooling outlet valve is provided on the cooling outlet pipe.

[0009] By adopting the above technical solution, the drying inlet pipe is controlled by the drying inlet valve, the drying outlet pipe is controlled by the drying outlet valve, the regeneration inlet pipe is controlled by the regeneration inlet valve, the regeneration outlet pipe is controlled by the regeneration outlet valve, the cooling inlet pipe is controlled by the cooling inlet valve, and the cooling outlet pipe is controlled by the cooling outlet valve.

[0010] Preferably, the cooling assembly includes a water-cooled tank, a drying spiral tube, and a cooling spiral tube. The water-cooled tank is connected to an inlet pipe and an outlet pipe. An inlet valve is installed on the inlet pipe, and an outlet valve is installed on the outlet pipe. The drying spiral tube and the cooling spiral tube are disposed inside the water-cooled tank. One end of the drying spiral tube is connected to an input pipe, and the other end of the drying spiral tube is connected to a compressed air pipe. One end of the cooling spiral tube is connected to a cooling inlet pipe, and the other end of the cooling spiral tube is connected to a cooling branch pipe. A cooling flow control valve is installed on the cooling branch pipe, and the cooling branch pipe is connected to an output pipe.

[0011] By adopting the above technical solution, the flow rate of gas in the cooling branch pipe is controlled by the cooling flow control valve. Most of the dry compressed air flowing into the output pipe is delivered to the gas-using equipment, while a small portion of the dry compressed air flowing into the output pipe is delivered to the cooling branch pipe. The dry compressed air in the cooling branch pipe flows into the cooling spiral tube, where it exchanges heat with the coolant in the water-cooled tank, thereby reducing the temperature of the dry compressed air in the cooling spiral tube. The cooled dry compressed air then enters the tank through the cooling inlet pipe to purge the adsorbent, further cooling it. The compressed air then flows into the compression spiral tube through the compressed air pipe, where it exchanges heat with the coolant in the water-cooled tank, reducing the temperature of the compressed air and minimizing the decrease in adsorbent drying efficiency.

[0012] Preferably, the cooling assembly further includes a reflux spiral tube, which is disposed inside the water-cooled tank. One end of the reflux spiral tube is connected to a booster pump, the output end of which is connected to the input pipe, and the other end of the reflux spiral tube is connected to the cooling outlet pipe.

[0013] By adopting the above technical solution, the dry compressed air after purging the adsorbent enters the return spiral tube through the cooling outlet pipe. The compressed air in the return spiral tube is cooled and pressurized by the coolant in the water cooling tank and then returned to the input pipe, reducing the loss of compressed air.

[0014] Preferably, a regeneration main pipe is connected to the regeneration inlet pipe, and a blower is connected to the end of the regeneration main pipe away from the regeneration inlet pipe.

[0015] By adopting the above technical solution, after the blower is started, the gas flows along the regeneration main pipe, regeneration inlet pipe, tank and regeneration outlet pipe, which facilitates the discharge of moisture in the adsorbent from the regeneration outlet pipe.

[0016] Preferably, a left end plate and a right end plate are rotatably arranged inside the tank, with the left end plate and the right end plate being arranged opposite each other. The microwave transmitter is fixedly arranged between the left end plate and the right end plate. A left rotating shaft is fixedly arranged at one end of the adsorption cylinder, passing through the left end plate and rotatably connected to the left end plate. A right rotating shaft is fixedly arranged at the other end of the adsorption cylinder and rotatably connected to the right end plate.

[0017] By adopting the above technical solution, when the tank is in the adsorbent cooling state, the left end plate and the right end plate rotate synchronously, causing the adsorbent layer in the adsorption cylinder to revolve. At the same time, the left and right rotating shafts rotate synchronously, causing the adsorbent layer in the adsorption cylinder to rotate, thereby facilitating uniform contact between the adsorbent layer and the cooling airflow.

[0018] Preferably, a drive motor is fixedly installed on the tank body, and the output shaft of the drive motor is fixedly connected to the end of the right end plate away from the left end plate. A right ring cover is rotatably installed on the end of the right end plate away from the left end plate. The right ring cover is sleeved on the output shaft of the drive motor, and the end of the right ring cover away from the right end plate is rotatably connected to the tank body.

[0019] By adopting the above technical solution, the drive motor is used to achieve the effect of driving the left end plate and the right end plate to rotate synchronously. At the same time, the right ring cover, the right end plate and the tank body protect the output shaft of the drive motor.

[0020] Preferably, a drive shaft is fixedly installed on the tank body, and the drive shaft is rotatably connected to the end of the left end plate away from the right end plate. A drive gear is sleeved on the drive shaft, and the drive gear is fixedly connected to the drive shaft. A transmission gear is fixedly installed at the end of the left rotating shaft away from the adsorption cylinder, and the transmission gear meshes with the drive gear. A left ring cover is sleeved on both the transmission gear and the drive gear. One end of the left ring cover is rotatably connected to the inner wall of the tank, and the other end of the left ring cover is rotatably connected to the end of the left end plate away from the right end plate.

[0021] By adopting the above technical solution, when the left end plate and the right end plate rotate synchronously, the transmission gear and the drive gear rotate relative to each other, thereby causing the transmission gear to drive the adsorption cylinder to rotate. At the same time, the left ring cover, the left end plate and the tank body provide protection for the transmission gear, the drive gear and the drive shaft.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses an energy-saving air drying device. (Refer to...) Figures 1 to 4The system comprises three tanks 1, which are used for compressed air drying, adsorbent regeneration, and adsorbent cooling, respectively. Each tank 1 contains a microwave transmitter 8 and several adsorption cylinders 9. The cylinder walls of each adsorption cylinder 9 are perforated, and the cylinders 9 are arranged in a circular array around the microwave transmitter 8. Adsorbent is filled inside each adsorption cylinder 9 to form an adsorbent layer 91, which is used to adsorb moisture. Each tank 1 has a drying outlet pipe 13, a regeneration outlet pipe 14, and a cooling outlet pipe 15 connected to its top. A drying outlet valve 131 is installed on the drying outlet pipe 13 to control its on / off state; a regeneration outlet valve 141 is installed on the regeneration outlet pipe 14 to control its on / off state; and a cooling outlet valve 151 is installed on the cooling outlet pipe 15 to control its on / off state. The bottom of tank 1 is connected to a drying inlet pipe 16, a regeneration inlet pipe 17, and a cooling inlet pipe 18. A drying inlet valve 161 for controlling the on / off state is installed on the drying inlet pipe 16, a regeneration inlet valve 171 for controlling the on / off state is installed on the regeneration inlet pipe 17, and a cooling inlet valve 181 for controlling the on / off state is installed on the cooling inlet pipe 18. A regeneration main pipe 31 is connected to the regeneration inlet pipe 17, and a blower 3 is connected to the end of the regeneration main pipe 31 furthest from the regeneration inlet pipe 17. An input pipe 11 is connected to the drying inlet pipe 16, and an output pipe 12 is connected to the drying outlet pipe 13. A cooling assembly 2 is installed on both the input pipe 11 and the cooling inlet pipe 18 to reduce the gas temperature.

[0033] When tank 1 is in a compressed air drying state, regeneration inlet pipe 17, regeneration outlet pipe 14, cooling inlet pipe 18, and cooling outlet pipe 15 are all cut off, while drying inlet pipe 16 and drying outlet pipe 13 are both open. At this time, the compressed air in the inlet pipe 11 enters the tank 1 along the drying inlet pipe 16, and the compressed air contacts the unsaturated adsorbent to achieve dehumidification and drying. The dried compressed air enters the outlet pipe 12 through the drying outlet pipe 13.

[0034] Once the adsorbent in tank 1 is saturated, tank 1 is adjusted to adsorbent regeneration mode. At this time, the drying inlet pipe 16, drying outlet pipe 13, cooling inlet pipe 18, and cooling outlet pipe 15 are all cut off, while the regeneration inlet pipe 17 and regeneration outlet pipe 14 are both open. The microwave transmitter 8 and blower 3 are started to allow the moisture in the adsorbent to be discharged through the regeneration outlet pipe 14.

[0035] After the adsorbent in tank 1 has been regenerated, tank 1 is adjusted to an adsorbent cooling state. At this time, the drying inlet pipe 16, drying outlet pipe 13, regeneration inlet pipe 17, and regeneration outlet pipe 14 are all cut off, while the cooling inlet pipe 18 and cooling outlet pipe 15 are both open. The gas cooled by the cooling component 2 enters tank 1 through the cooling inlet pipe 18 to purge the adsorbent, thereby cooling the adsorbent. The gas after purging the adsorbent is discharged from tank 1 through the cooling outlet pipe 15, reducing the decrease in adsorbent drying efficiency.

[0036] To achieve the effect of cooling the gas, refer to Figures 1 to 3The cooling assembly 2 includes a water-cooled tank 21, a drying spiral tube 22, a cooling spiral tube 23, and a return spiral tube 24, which are disposed inside the water-cooled tank 21. An inlet pipe 211 and an outlet pipe 213 are connected to the water-cooled tank 21. An inlet valve 212 for controlling the on / off state is installed on the inlet pipe 211, and an outlet valve 214 for controlling the on / off state is installed on the outlet pipe 213.

[0037] Reference Figures 1 to 3 One end of the drying spiral tube 22 is connected to the input pipe 11, and the other end of the drying spiral tube 22 is connected to the compressed air pipe 221. Compressed air flows into the compressed spiral tube through the compressed air pipe 221, and the compressed air in the compressed spiral tube exchanges heat with the coolant in the water-cooled tank 21 to reduce the temperature of the compressed air.

[0038] Reference Figures 1 to 3 One end of the cooling spiral tube 23 is connected to the cooling inlet pipe 18, and the other end is connected to a cooling branch pipe 231, which is connected to the outlet pipe 12. A cooling flow control valve 232 is installed on the cooling branch pipe 231 to control the flow rate of the gas in the cooling branch pipe 231. Most of the dry compressed air flowing into the outlet pipe 12 is directed to the gas-using equipment, while a small portion is directed to the cooling branch pipe 231. The dry compressed air in the cooling branch pipe 231 flows into the cooling spiral tube 23, where it exchanges heat with the coolant in the water-cooled tank 21, thereby reducing the temperature of the dry compressed air in the cooling spiral tube 23. The cooled dry compressed air then enters the tank 1 through the cooling inlet pipe 18 to purge the adsorbent, further cooling the adsorbent and reducing the decrease in adsorbent drying efficiency.

[0039] Reference Figures 1 to 3 One end of the return spiral tube 24 is connected to the cooling outlet tube 15, and the other end of the return spiral tube 24 is connected to a booster pump 241. The output end of the booster pump 241 is connected to the input tube 11. The dry compressed air that has purged the adsorbent enters the return spiral tube 24 through the cooling outlet tube 15. The compressed air in the return spiral tube 24 is cooled by the coolant in the water-cooling tank 21 and pressurized by the booster pump 241 before flowing back into the input tube 11, reducing the loss of compressed air.

[0040] To ensure uniform contact between the adsorbent layer 91 and the cooling airflow, refer to Figure 4A drive motor 6 and a drive shaft 7 are fixedly installed on the tank body 1. A right end plate 5 is installed on the output shaft of the drive motor 6, and a left end plate 4 is rotatably mounted on the drive shaft 7. Both the left end plate 4 and the right end plate 5 are located inside the tank body 1, with the left end plate 4 and the right end plate 5 positioned opposite each other. A microwave generator is installed between the left end plate 4 and the right end plate 5. A right rotating shaft 51 is fixedly installed at one end of the adsorption cylinder 9, and the right rotating shaft 51 is rotatably connected to the right end plate 5. A left rotating shaft 41 is fixedly installed at the other end of the adsorption cylinder 9, passing through the left end plate 4, and is rotatably connected to the left end plate 4. A drive gear 71 is sleeved on the drive shaft 7, and the drive gear 71 is fixedly connected to the drive shaft 7. A transmission gear 72 is fixedly installed at the end of the left rotating shaft 41 away from the adsorption cylinder 9, and the transmission gear 72 meshes with the drive gear 71. When the tank body 1 is in a cooled adsorbent state, the drive motor 6 starts, driving the left end plate 4 and the right end plate 5 to rotate synchronously, causing the adsorbent layer 91 inside the adsorption cylinder 9 to revolve. Simultaneously, the transmission gear 72 and the drive gear 71 rotate relative to each other, causing the transmission gear 72 to drive the adsorbent layer 91 inside the adsorption cylinder 9 to rotate. By rotating and revolving within the tank 1, the adsorbent layer 91 achieves uniform contact with the cooling airflow.

[0041] refer to Figure 4 A left annular cover 42 is fitted onto both the transmission gear 72 and the drive gear 71. One end of the left annular cover 42 is rotatably connected to the inner wall of the tank 1, and the other end of the left annular cover 42 is rotatably connected to the end of the left end plate 4 away from the right end plate 5. The left annular cover 42, the left end plate 4, and the tank 1 provide protection for the transmission gear 72, the drive gear 71, and the drive shaft 7. A right annular cover 52 is fitted onto the output shaft of the drive motor 6. One end of the right annular cover 52 is rotatably connected to the tank 1, and the other end of the right annular cover 52 is rotatably connected to the end of the right end plate 5 away from the left end plate 4. The right annular cover 52, the right end plate 5, and the tank 1 provide protection for the output shaft of the drive motor 6.

[0042] The implementation principle of an energy-saving air drying device according to an embodiment of this application is as follows: When the tank 1 is in a compressed air drying state, the regeneration inlet pipe 17, regeneration outlet pipe 14, cooling inlet pipe 18, and cooling outlet pipe 15 are all in a cut-off state, while the drying inlet pipe 16 and drying outlet pipe 13 are both in a conductive state. At this time, the compressed air in the input pipe 11 enters the tank 1 along the drying inlet pipe 16, and the compressed air contacts the unsaturated adsorbent to achieve the purpose of dehumidification and drying. The dried compressed air enters the output pipe 12 through the drying outlet pipe 13. When the adsorbent in the tank 1 is saturated, the tank 1 is adjusted to an adsorbent regeneration state. At this time, the drying inlet pipe 16, drying outlet pipe 13, cooling inlet pipe 18, and cooling outlet pipe 15 are all in a cut-off state, while the regeneration inlet pipe 17 and regeneration outlet pipe 14 are both in a conductive state. The microwave transmitter 8 and the blower 3 are started to discharge the moisture in the adsorbent through the regeneration outlet pipe 14. When the adsorbent in the tank 1 is regenerated, the tank 1 is adjusted to an adsorbent cooling state. At this time, the drying inlet pipe 16, drying outlet pipe 13, regeneration inlet pipe 17, and regeneration outlet pipe 14 are all in a cut-off state, while the cooling inlet pipe 18 and cooling outlet pipe 15 are both in a conductive state. The cooling airflow enters the tank 1 through the cooling inlet pipe 18 to purge the adsorbent, thereby cooling the adsorbent. The gas after purging the adsorbent is discharged from the tank 1 through the cooling outlet pipe 15, reducing the possibility of a decrease in the drying efficiency of the adsorbent.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
